Yes I have been able to instruct them on what to do every time. Also of particular note is that normally outside of the US, if I bypass the pin more than 3 times, the card gets blocked. Here in the US it doesn't matter how many times they bypass it, which happens a lot especially with tip adjust establishments like restaurants or spas. What is also peculiar is that if pin is entered on a tip adjust, it still prints a receipt with a tip box but no signature. I wonder how they'd prove that it was the cardholder that entered the tip in cases of chargeback with no signature.
